  • Good driver for many appliances

    posted by Cy4n1d3

    This driver works great for me. It doesn't get to hot due to the heatsinked mosfet and it delivers stable power, about 640mA for me.I used it to drive a multitude of led lights and it worked well for http://www.dx.com/p/10w-1050lm-3000k-1-led-warm-white-light-ceiling-spotlight-lamp-yellow-silver-dc-12-14v-195839There also is a fuse on the pcb which should prevent damage to the led parts - at least once!
    More versions of this would be great (~750mA, 1A or even a dimmable/configurable version)! The heatsinks works quite well for this one, so no fear of dieing drivers yet :)
    +stable current delivered+heatsinked+fused- none!There are cheaper drivers to be had out there, but this one delivers what it promises and keeps cool while doing that. I can recommend it!
  • If it works, then good ...

    The switching power supplies hold the voltage between idle and full load, good constant.
    Return is too complicated, not worth it at this price.
    I would buy the device again, but I need to provide reserve.
  • Cheap, good, easy to use

    Easy to use, powerful, well manufactured. Gives a stable current, when connected to the spotlight the produced light is bright and smooth, no blinking, no flickering, just a good quality light.The device is fused (soldered fuse on a high voltage cirquit), wires are good quality and have thick insulation, CE Certificate is important for European customers
    I've already purchased 10+ devices :) The first batch of 2 pcs contained units of different - much worse - internal design, the produced light was awfully blinking at 100Hz, causing eye fatigue. Fortunately, all devices in next orders were perfect!
    Very good unit! I recommend it for all who want to make DIY energy saving, inexpensive spotlight
  • Perfect for this price

    I've used this for powering my 5m long RGB-led strip (*). Works perfect, no sounds, does not get hot (just mildy warm). Contacts are of decent quality. Alltogether the weight is low, very useful for mounting, very decent product and good price.(*):Waterproof RGB 300x5050 SMD LED Multicolored Light Strip (5-Meter/DC 12V) Objectnr./SKU 904441522
    none really
    Decent product, good quality, good price. Don't hesitate to buy.

    Small and useful. Not so expensive in price for that quality. It is not one-triode-chip-chinese-design. Low heat generation. No noise. Quality and easy to disassemble housing.Long wires with enough thickness.
    Housing seems to big for PCB inside :)) There are place inside enough for two drivers.
    Good small sized and high quality device. In space sensitive applications you can just remove housing.
